Magnetically coupled pumps for leak-free pumping

Castle Pumps has been a supplier of quality and reliable magnetic drive pumps for over 15 years. As they are otherwise known, magnetically coupled pumps don’t have a mechanical seal, which eliminates the chance of leakages, making it a perfect chemical pumping solution for aggressive fluids that can be potentially dangerous if leaked. They are also ideal for applications where fluids may crystallise if exposed to the air. We offer a range of magnetic drive pumps designed for long service life in hazardous industrial process and flammable environments, with the added benefit of low maintenance due to the lack of seals that are prone to wear and need replacing. If you have an application that benefits from a magnetically coupled pump over a mechanical seal solution, then look no further than our mag pumps.

FAQs

Rather than having a mechanical seal to prevent liquid escaping from between the motor and pump shaft, magnetically coupled pumps use two magnets. The absence of mechanical seals that are prone to wear reduce the chance of leaking and maintenance.

The drive magnet is attached to the shaft operated by the motor. As the motor turns on, it spins the drive magnet which in turn spins the magnet attached to the impeller. The rotation of the impeller produces the power that drives the liquid through the pump.

Due to their seal-less design meaning they are not prone to leaks, magnetic drive pumps are very popular for the pumping of flammable, toxic and hazardous chemicals, acids and other potentially dangerous fluids that do not contain abrasives.

No! The presence of solids can stick to the magnets and interfere with the operation of the pump.

Under extremely high temperatures or excessive torque the magnets may decouple meaning that the pump shaft can slip causing stoppages and inefficiencies.
